The Benjamin Bulldog and Benjamin Rogue are said to be engineered around the Benjamin Nosler bullet. During the time of the Benjamin Rogue .357, Crosman even sold rebranded Air Venturi cast bullets for use in this gun. As such, is it safe to say that the barrel in the Bulldog and Rogue are similar to the FX smooth twist X barrel, in that they are designed for cast and swagged ammo as opposed to diabolo style pellets? Both guns shoot diabolo style pellets very well also, but I am question the specific engineering or design of their barrels. Thanks for all constructive responses in advance!
